Hi Matt Eicholtz, it's a great problem. but the testsuite results look strange for me: According to this site:http://www.mathworks.com/matlabcentral/cody/badges/3?page=120, the last solver badge on 26 Jan 2012(for Solution 7330) is the 266th of all.Did I miss something? Thank you.
LY Cao, hmm...that's strange. I am wondering if the Cody pages are not all up-to-date. I was using the Recent Activity pages. Let me look into it; I may just add some tolerance to the test suite results.
In the meantime, perhaps someone from MathWorks can comment on the discrepancies between various Cody sites. For instance, the link LY Cao posted shows 15128 players earned the Solver badge (as of now), but this link (http://www.mathworks.com/matlabcentral/cody/activities?sort=&term=type%3ABadge) only accounts for 7962 total badges earned.
yes,it's very strange,at the bottom of that page it shows "5951 – 6000 of 6,245"
Somewhere between 2014-2015 cody activity pages lost about 150k entries i believe it happened when cody suffered from spamming attack. http://www.mathworks.com/matlabcentral/trendy/plots/675 According to this plot, it was about a half of entries cody had that time. (Perhaps "too strong" antispam filters?) Lot of other things were affected too. You cannot see some older solutions (sometimes direct link works, if you know the solution number). Here is another good example: http://www.mathworks.com/matlabcentral/cody/badges/12 http://www.mathworks.com/matlabcentral/cody/players?term=badge%3A%22Celebrity%22
How many players awarded this badge? 5? 10? 11?
By now probably the most accurate data are stored in José trend http://www.mathworks.com/matlabcentral/trendy/trends/2048 which is recording since July 2013
